Shell Programming and Scripting

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Code:

chmod a+rx  readLine.sh

and execute it.
When you say
sh script, you will use sh, not script 1st line shell, and it looks that your sh is something, not bash or ksh.

If you like to run using bash then call
bash readLine.sh

Two method to run script:
1. add exucute priviledges for script file and 1st line include the interpreter path and excute syntax (sh, bash, bash, ksh, awk, perl, php, ...)

Code:

chmod a+rx somescript

1st line:

Code:

#!/usr/bin/some_interpreter

ex. to run:
./somescript

2. method is to start interpreter and give commands in textfile, commandline syntax is not same for every interpreter, but for shells it's always:

Code:

interpreter inputfile

ex. bash bashscript

Thanks dude.
check this

my shell is bash

Code:

    echo $SHELL
    /bin/bash

so iam using bash shell , and u said i changed the permissions to the file as a+x , still the output not showing the updated variables .
but when i run the script with

"bash readLine.sh"

It is showing the correct output .

correct me if i'm wrong.

Thanks Dude

i use bash and your original script works fine. are you sure "input.txt" contains lines? or does it even exists?

Code:

-bash-3.2$ ./test
 i Value =5
 Count Value = 15
-bash-3.2$ cat test
count=0
i=0
while read line
do
i=`expr $i + 1`
count=`expr $count + $i`
done < input.txt

echo " i Value =$i "
echo " Count Value = $count"
-bash-3.2$ ./test
 i Value =5
 Count Value = 15
-bash-3.2$

Thanks buddy,
ya input.txt has lines , and u r code working fine ..
Thanks a lot guys .. keep the spirit
